One object of the invention is to provide means for controiiing the automatic tion of the throttle veive by means of the p gessure in the oiling system.

Another object of the invention is ie provide a simpie end eiiioient embodiment eif' the means for carrying one the above end,

Wioh these objects and others in iew, the invention is embodied; in preferable. form in ile construction and ei'iengement hereinafter deseiibed and iliustmteti in the accompanying drawings, in 'whieiiz Fig. 1 is an end ViTV in eievebion of 2. i13 oroearbon mom; showing an oil pump and part of the oil circulation system and show ing, in vertical section, the oii operating cont-rollingihe ithrottie Fig. QUs asection on line of Fig. l,

Referring to the drawings, 10 indicates an oii pump adapted 0 be employed in com nection with a hydrocarbon motor 11, and ririven from the shaft 19. thereof.

An oil conduit 13 iezuis from the pump 0 snitebie eiizinneis ieuiing $0 iiiie bezirings and other parts of the motoi. interposed in said conduit and communicating; therewith, is a. casing 14 having a passageway 15 fame in; pzirt'of the main. conduit. Communicaiin; with this passageway is opening 16 closed by a screw ping- 17 havingstem 18. {in the opposite side of the casing and lead. ing into the passageway is a projeeting providing a fixed and always open by-pass 1.9 which may lead back to the pump or other park: of the circulation system. lay-pass has an opening or". known. area. and which area has a certain definite i'elzition'to the revolutions per minute of the engine so that a predetermined amount of oil at a. pie determined pressure will pass freely througi: the opening. This fixed bypass films serves by this extra one in as a measuring passageway for the oii iiniieif e pressure and e of An e ii 0'; (is 2mm the '7 s oioeeri ii-y m ifiee yoess chamber slide u oi, v to be pressed i Wei-rd :igeinsi the stem by one enoi 3 me other end the siieii. piston 5" adapted to move over 2.

and means connected to said member for operatlng said throttle.

2. In combination with a hydrocarbon motor, an oil circulation system for lubrieating said motor having a valve, said valve having means for by-passing the oil and means movable by the oil pressure in excess of a predetermined pressure for controlling the speed of the motor.

3. In combination with a hydrocarbon motor, an oilcirculation system for lubri eating saidmotor, a conduit adapted to re-- ceive oil from, and return oil to, said systerm, a plurality of by-passeslead'ing from I said conduit. into said system, certain of said by-passes being adapted to return a predetermined quantity of oil to said system and certain others of said by -PdSSBS being adapted to return-oil to said system after a predetermined oil pressure has been reached, and means-controlled and operated by the oil pressure in excess of said prede termined pressure for controlling the motor.

4. In combination with a hydrocarbon motor, an oil circulation system for luhri'catin said motor, a valve unit mounted in sai system and comprising a member having a hy-pass normally open and adapted to pass a predetermined quantity'ot' 'oiLat a-pressure not exceedin a predetermined oil pres sure, and a seconc by-pass, normally closed, a valve in said second by-pass, operable by l the oil pressure in excess of said predate mined pressure, to uncover the opening n said by-pass for controllin the motor. 5. In combinatlon'with a liydrocarbon motor having controlling means, an oil circulation system for lubricating said motor, a valve unit disposed in the path of circulation of the oil insaid system. and comprising a main conduit, a bypass opening into said conduit and adapted to permit the passage of oil at a pressure not exceeding a predetermined pressure, a lateral conduit opening into said main conduit, a valve positioned in said lateral conduit and adapted to be operated by the oil pressure in excess of said predetermined pressure and operative connections between said. valve and the controlling means for said hydrocarbon motor.

6. In combination with a hydrocarbon motor having controlling means, an oil circulation system for lubricating said motor, a valve unit disposed in the path of circulation of the oil in said system and comprising a main conduit, a by-pass opening into said conduit and. adapted to permit the passage of oil at a pressure not exceeding a predetermined pressure, a lateral conduit opening into said main conduit and havin a second by-pass opening, avalve normal y closing said second byass and adapted to be operated by the oi pressure in excess of said predetermined pressure, and operative connecti'ons between said valve and the corn trolling means for said hydrocarbon motor. in testimony whereof I affix my signature.
